Frequency domain control design methods

Problem. Consider the DC motor from HW1, now with the parameters

(the difference is hat L_a = 0 now). The requirements remain the same:
• an integral action in R(s),
• high-frequency roll-off of at least 1 for R(s),
• µm ≥ 0:5 <=> |S.jω| ≤ 2 for all ω,
• |Tc(jω)| ≤ 1 for all ω.

Using the H_∞ loop-shaping procedure, design a controller satisfying these requirements. Try to maximize the resulting crossover frequency ω_c. Explain your design choices.

Besides a brief file with explanations, submit a MyName.mat (with your name in place of "MyName") file having LTI 3 systems in it:
• the plant, named G
• the controller, named R
• the final weight used in the design, named W
